Overview
The DG442LEDQ-T1-GE3 is a monolithic quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a normally open configuration and operates on single supplies from 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device provides an on-resistance of 16 Ω, turn-on time of 18 ns, and charge injection below 8 pC. It is housed in a 16-lead TSSOP package with tape-and-reel packaging.
Feature Summary
- Low parasitic capacitance for minimized switching glitches
- TTL and CMOS logic compatibility
- Fast switching speed with low signal distortion
Applications
- Data acquisition systems
- Sample-and-hold circuits
- ADC input circuit designs
- Automatic test equipment
Procurement Notes
Verify the specific suffix 'T1' confirms the tape-and-reel packaging format containing 3000 units per reel. Confirm the 'D' temperature range covers -40 °C to +85 °C operation. Ensure RoHS compliance status matches project requirements as indicated by the 'E3' designation.
Selection Notes
Select this component when a normally open SPST configuration is required. Compare against the DG441LE variant if a normally closed function is needed instead. Verify that the 16 Ω on-resistance meets the signal integrity requirements for the target application voltage range.
Part Context
This part belongs to the DG441LE/DG442LE family of precision monolithic quad SPST CMOS analog switches. The series is designed for high-speed, low-error switching applications requiring wide dynamic range and low power consumption across various industrial and medical environments.
Replacement Considerations
No direct pin-for-pin replacements are documented in the provided datasheet. Designers should evaluate alternative quad SPST analog switches from other manufacturers based on matching on-resistance, supply voltage ranges, and package dimensions.
